The dark heavenly river is boundless, and the unknown matter is all over it, and the vast and boundless, whether it is up or down, left or right, you can't see the edge. In the dark heavenly river, from time to time, a beam of light of different colors passed through and disappeared in the blink of an eye.

This is the edge of the Tianhe River, and the environment is extremely harsh, and there is not a single intact star system.

There are only countless large and small celestial bodies scattered here in an irregular manner, most of which are extremely cold rocks and ice, and occasionally a comet with a long tail can be seen plunging into the heavenly river and disappearing without a trace in an instant.

Here, the matter of the Tianhe River no longer only exists in the Tianhe, and a large cloud of lightless dark matter scattered from the Tianhe can be seen everywhere, floating motionless in the starry sky.

Occasionally, celestial bodies come in orbit and come into contact with these substances. With the slightest touch, the dark matter will engulf and dissolve the parts of the celestial body in contact in a very short time. After the celestial body moved away, the place where it touched the dark matter became a large crater, like an apple that someone had bitten into. And the dark matter has quietly grown a little stronger.

If this continues, after a few tens of millions of years, I am afraid that the dark matter will grow bigger and bigger, and eventually border the Tianhe.

Dark matter is all-engulfing, whether it is meteorites, ice, gas, or light, it will be absorbed and swallowed by it. Even the stars that are burning hot, they can't stop the devouring of dark matter, and they will disappear little by little, and in no more than a hundred years, an incomparably huge star will be completely turned into a part of the heavenly river.

No one knows what those dark matter are, and the people who try to study these things have become part of the Tianhe.

No one dares to come here in such a Jedi. No one will come here to study even the most dedicated scientists, when the conclusions of countless of their predecessors who have come to the cost of their lives are on their tables.

A fleet, flying slowly.

They were so slow that even the transports laden with supplies were a few points faster than them.

The size of the fleet was not large, there were only a thousand ships. These spaceships look exactly the same, and in such a precipitous place, they are like nimble little fish, shuttling through them. In the face of the dark matter that could easily destroy them, no ship would be afraid. They were fearless, like walking a tightrope, flying dangerously in it.

This fleet, after separating from Xu Tianyuan and the others, went to find Lin Moxue's Yunyi and the battleships he took away.

Three days ago, the fleet quietly arrived at the Zhengzhou Star Domain, forced an ordinary passenger spaceship, and picked up more than a dozen cavalry regiment soldiers from the ship. Then, according to the fleet plan provided by the soldiers of the cavalry regiment, Yun Yi immediately set off with a certain position on the fleet plan. They had arrived three hours earlier. When they first arrived, the ubiquitous danger startled almost everyone, but soon, after judging that the dark matter didn't move casually, they breathed a sigh of relief, slowed down their speed, and shuttled through it.

Since entering here, Yun Yi's face has not looked good, and he has been tense all the time.

Hiluffis walked up to him with a teacup and handed it over.

Taking the teacup, Yun Yi took a sip, the temperature was not high or low, the tea was fragrant, and it was completely the top tea making skills. It's just that at the moment, he has no interest in tasting tea. When he thought that Lin Moxue had been walking on such a dangerous ground for a long time, he felt a thrill in his heart. With only a thousand warships with me, it was so difficult to go. And Lin Moxue's fleet is nearly 10,000 ships, and there is the enemy's pursuit behind her, how did she pass through these places?

"Boss." Hiluffis raised her head and shouted, her bright eyes looking at him: "Sister Lin will definitely be fine." ”

Yun Yi smiled and gently stroked her hair. Hiluffis's stature is not high, only reaching Yun Yi's shoulders, so Yun Yi can touch her hair as soon as he reaches out, and for a long time, it has unconsciously become a habit for him. However, Cerumis did not dislike his action, but enjoyed it, and every time he touched her hair, her eyes would squint together, like a kitten being petted.

"Is Victor here?"

Syrophys replied, "He has been informed, and it will probably be soon." ”

As soon as she finished speaking, the door to the command room opened, and a young man in military uniform without rank strode in, carrying a white medal on his chest, on which was painted a shield and crossed double swords, and below the pattern was a small golden shield, which represented that he was a detachment commander of the Martial Thunder Cavalry Regiment, and in the official establishment of the cavalry regiment, a battalion commander, whose emblem was a golden shield.

In the cavalry regiment, you can get such a medal by becoming a reserve member, the main body of which is made of a space device, which stores his own Wulei mecha. However, the front emblem of the reserve member only has a large shield and two swords, and the underside is blank. Only after becoming a full member will a small silver sword be added. Every twenty people in the cavalry regiment are a squad, and the outstanding members are selected as the squad leader, and the squad leader's logo is the same as the official members, which can be replaced at any time, which is also a way to motivate everyone to grow.

Five squads are divided into a platoon, and the platoon commander's emblem has two silver swords. The platoon commander is the company commander, who manages five platoons, and is marked by three silver swords. At the top was the battalion commander, and the emblem was replaced by a golden shield, and now there were only ten battalion commanders in the entire cavalry regiment, that is, ten detachment commanders at the beginning of its establishment. The battalion commander is the regiment commander when he goes up, and the symbol is two golden shields, and now there is only one person in the department.

"Report to the boss, Viktor, the commander of the 10th Battalion of the Vulei Cavalry Regiment, came to report."

Yun Yi nodded, looking at the tall young man with short chestnut hair in front of him with a calm face.

This time he came to the Northern Universe, and he only brought three battalions of the cavalry regiment with a total of 6,000 people. In addition to the 3rd Battalion of Shessimyu, there was also Mary's 5th Battalion and Victor's 10th Battalion. The 10th Battalion was originally left at the Tower Shield Military Academy to train new members, but after receiving the order, they immediately rushed to the Unicorn Fortress and joined Yunyi to come to the Northern Universe together. And the soldiers of the cavalry regiment that Yunyi received when intercepting the passenger spacecraft before were led by Victor.

"Victor."

Cloud Wing led him to the porthole, pointing to the dark matter that was everywhere outside.

"Have you seen any of these things before?"

Victor glanced at it and smiled, "Of course I did." Speaking of which, under the leadership of Miss Lin, we have been flying along the banks of the Tianhe River since we left the space station of the mining group. This kind of thing is all too common, but be careful, if the ship touches it, it will slowly erode and be completely devoured and dissolved within an hour......"

"Wait!"

Yun Yi was keenly aware of a question: "You mean that the spaceship can last in this substance for an hour before it is swallowed?" ”

"yes, what's wrong?"

Victor looked at his boss suspiciously, but quickly understood, and said with a smile: "Speaking of which, when we first arrived at the edge of the Tianhe, we were all very frightened when we saw those meteorites being swallowed in an instant. But there is no way to be afraid, the pursuers behind are like wolves and tigers, and they can't run if they don't run. We had more than 9,000 warships, and a few minutes later a ship came across, but we were very surprised that the ship was not swallowed up immediately, only the parts that came into contact with the matter dissolved slightly, but it was very slow, and the ship left quickly. ”

"How is this possible?"

Yun Yi was very puzzled, since those substances could devour all kinds of celestial bodies, there was no reason why they couldn't devour the battleships with metal shells. You must know that the materials of those meteorites are different, and there are also large amounts of metals in them.

"Boss, what I said is true, if you don't believe me, you can ask others."

Victor said hurriedly.

"It's okay, I believe what you say, but there must be something to do with it, and I have to figure it out."

Yun Yi said softly.

After thinking about it, Cloudwing summoned the ship's captain and asked him to shoot a lifeboat at a cloud of dark matter. The material of the lifeboat is also made of alloy, and although it is not as strong as the outer armor of the battleship, it is also very tight and not easy to fall apart.

After the lifeboat was ejected, it did not start its engine, but used the inertia of the ejection to rush towards a large cloud of dark matter not far away.

Yun Yi's eyes stared at the lifeboat without blinking, and Syrumis next to him also looked curiously.

Suddenly, the lifeboat plunged headlong into the mass of matter.

Victor's eyes immediately widened, almost in disbelief, and he muttered blankly, "How is it possible, this is completely impossible." ”

In the distance, small lifeboats, like chips of wood that had fallen into the lava, dissolved almost instantly, and then swallowed up as part of the mass.

Several people around him, like the captain, like the few crew members who had just heard their conversation, glared at Victor. If the ship could last in that substance for a while, as he said, I'm afraid they wouldn't even know how to die.

"I, I, I...... I really didn't lie to everyone. ”

Victor was stunned, he never expected this to be the result. However, when he was in Miss Lin's fleet before, he saw with his own eyes that there were spaceships passing through the substance, and there was more than one!

"Boss, I'm ......"

The young battalion commander's face turned red with anxiety, but the truth was right in front of him.

"Everyone, be quiet." Yun Yi waved his hand and suddenly smiled: "I believe what Victor said is true. Alright, that's the end of this, Syrumis, inform, and tell all ships to avoid the black matter as much as possible. I'm going to modify the route and pass through places where there's less substance. ”

With that, as if he had been given something amusement, he took Syrumis by the hand and walked towards the room.

Only Victor stared out the window blankly and said aggrievedly.

"I ...... I'm really not lying......"
